LANTERN.

SPECIFICATION forming part'of Letters Patent No. 503,780, dated rAugust22, 1893.

Application led June 1, 1893. Serial No. 476,207- (No model.)

To @ZZ whom t may concern,.-

Be it known that I, ALBERT ZIMMERMANN, a subject of the King ofWrtemberg, and a resident of Stuttgart,- Wiirtemberg, Ger-V many, haveinvented certain new and useful Improvements in Lanterns, of which thefollowing is a specification. This invention relates to an improvementin lanterns; and the lobject of my invention 1s to provide alanternwhich is so constructed that in case the lantern is upset or inclinedvery much to one side it is extinguished automatically and thus there isno danger whatever that the oil running from the lamp can be ignited andexplode.

The invention also consists in the construct1on and combination of partsand details which will be fully described hereinafter and iinallypointed out in the claims.

In the accompanying drawings, Figure l is a vertical transversesectional view of myimproved lantern in upright position. Fig. 2 is aside-view of the same, on a smaller scale and showing it resting on itsside. Fig. 3 is a vertical transverse sectional View of the lamp ininclined position. Fig. 4 is an enlarged detail sectional view of thelantern frame, and Fig. 5 is a horizontal sectional View through thesame, showing the locking spring.

Similar letters of reference indicate corresponding parts.

On the bottom of the lantern A, an inverted approximately V-shaped wireB is fastened at each corner, the inner shanks of said V-shaped wires Bpassing through eyes D projecting from the side of the lamp b, so thatthe lamp can move up and down on the inner shanks of said wire B. Theburner a of the lamp is not provided with a fixed cap, as is usual,buthas its cap c connected with the remaining parts of the burner by a balland socket joint. Said cap c is made conical and is provided at itsbottomwith an outwardly-proj ecting iiange d, which can slide up anddown in the cylindrical shell e of the burner, which shell is drawn inat the top to form the ange g. A wick f passes up through the burner, asshown.

If the lantern is inclined or placed on its side, as shown in Fig. 2,the lamp is inclined to such an extent that the upper eyesDslide to theangle of the upper V-shaped wires B and the eyes that are at the lowerpart of the lamp, in the position shown in Fig. 2, rest against thebottom of the lantern. The burner-cap c, under the action of gravityswings to one side, so that the said cap passes over the wick guide, asshown in Fig. 3. The iiange d of part of said cap rests against theinner ange g of the burner shell and the other part of said iiange grests against the bottom of the interior of the shell, thereby shuttingoff all air from the burning end of the wick, causing the flame to beextinguished.

The lantern is preferably made conical or tapering shape, so as torender it .more diiiicult to upset the same.

The oil is poured into the lamp through the side filling tube E, whichis so located that the oil can be filled into the lamp only up to thelevel of the line m, whereby .an air space is at all times arrangedbetween the surface of the oil and the top of the lamp, which preventsthe overheating of the oil by the iiame and also prevents undueevaporation of the oil. The lamp contains a tube u for carrying thevapors of oil that may be generated, the upper end n of said tube ucommunicating with the interior of the lamp at the top and the lower endcommunicating with the exterior air at o. As the vapors can pass off anoverheating and explosion are prevented, and at the same time the tube uis so arranged that under no circumstances can the oil from the lamppass out through the same. As the lamp is heldin the lantern by the eyesand the V-shaped wires B, it cannot be removed from the lantern and betampered with.

The several parts forming the lantern are securely folded and rivetedtogether and the lantern is provided with a specially constructed hoodto prevent drafts aecting the dame. The door is held closed by a springrod t' fastened to the left-hand corner rod of the lamp frame andpassing through the same as at 7e, the upper end of said wire being bentto form a rounded hook Z, as shown in Fig. 5. To open the door, all thatis necessary is to pull the same against the hook, which is forced toone side to permit the door to pass, and in closing it is only necessaryto push the door into its opening, when the swinging edge of the dooracts on the hook Z and pressesthe same to one side. The springt thensnaps back and keeps the door in closed position.

' Patent;-

l. In a lantern, the combination, with a lantern frame, of invertedV-shaped wires fastened on the bottom of the lantern frame, and a lampprovided with protecting eyes that are guided on the inner Shanks ofysaid Wires, substantially as set forth.

2. The'combination, with a lantern frame, of inverted V-shaped Wiresheld on the bottom of the same at the corners,a lamp having eyesmountedv to slide on said Wires, and a tilting burner cap on vthe burnerof the lamp, n substantially as set forth.

3. The combination, with a lantern frame, of a lamp held on the bottomof thesame by wires fastened to the lantern frame and passing througheyes of the lamp, a burner shell,

and a sliding and tilting burner cap in said lantern frame and passingthrough eyes of said lamp, a burner shell on the lamp, thetop of whichburner shell is bent inward to form a flan ge, and a conical burner-capin said shell, the bottom edge of said cap being bent outward to form aiiange, to permit said cap to slide up and down in the shell and to betilted in the same, substantially as set forth.
